IMPROVEMENT IN LUBRICATORS.

Specification forming part of Letters Patent No. 36,703, dated October 2l, 1862.

" 0 all whom ifm/ay concern:

Be it known that I, AUGUsr CONRAD DE- WIEs, of Orefeld, inthe Kingdom of Prussia, have invented a certain new and useful Improvement in .Lubricators, of which the following is a full, clear, and exact description, reference being had, to the accompanying drawings, which make part of this specifica tion, and in which- Figure l represents a vertical longitudinal section through my improved apparatus at the line x a: of Fig. 2; and Fig. 2 a vertical transverse section through the same at the line y y, Fig. 1.

The lubricating devices heretofore employed require the use of so much oil that it Hows .through the oiling-hole as well during the repose of the axle as when it is in motion. This waste, besides being quite useless and unnecessary, makes the machinery near the oil-cups very dirty and greasy. Plates or drippingpans are sometimes placed under the axleboxes to catch the drippingsgbut this cannot be done perfectly without a great deal oftroublc and expense; Again, in many manufactories the axle-boxes are mostly either in dark rooms or at a considerable height from the ground. As it is difcultto inspect such boxes even with the aid of a stair or ladder and a light, the journals are often allowed to become heated before their want oflubrication is dis covered.

lt is the object of my invention to avoid the above-mentioned and other defects incident to lubricators constructed as hereinbefore described,` and to provide a simple, cheap, and efficient lubricating apparatus, to which end my improvement consists in the employment of a glass vessel into which a tube or cylinder is inserted, the mouth of the vessel beingclosed with a cock through which the tube passes. The end of the tube which is inserted into the vessel is closed, with the exception of a mi` nute orifice. Asimilar orifice, through which the oil escapes,is also made in one sideof the tube. Thellower or outer end of the tube is open and iits closely upon lthe axle to be lubricated, so that when in repose no oil escapes; but when the axle rotates the oil is drawn down and lubricates the journal, the vacuum thus caused in the vessel being filled by the air which percolates through the cork.

.In the accompanying drawings my improved apparatus is shown as consisting of a bottle, A, the mouth of which is fitted with a cork, O, through which a tube, B, passes. The upper end of this tube is closed, with the exception of a minute opening, through which the oil flows. A similar aperture is also made in the side of the tube. The outer end ofthe tube is open and iits accurately upon5 the shaft E.

The operation of the lubricator is as follows: The bottle A is iilled With oil and the cork C and tubeB inserted into it. The bottle isthen turned upside down and the tube B inserted into a hole in the axle-boxV D in such manner that its mouth fits closely upon the shaft E. As the shaft revolves "the oil is drawn down hy the suction thus produced, and lubricates it; but when the axle ceases to rotate the ilow of oil is also stopped, the vacuum created by the liow of oil being filled by air which percolates through the cork.

The advantages attained by the use of my improved apparatus are perhaps greater than would strike a casual observer. Owing to the transparency of the oil-cup, a glance serves to show the` quantity of lubricating material it contains,no1natter Where situated. The construction of the lubricator, moreover, is so simple that it can be made or repaired by any person of even the most ordinary ability.

Thesaving of oil by the use of myinvention is very great, amounting, as I have demon strated by experiment, to at least one-half the quantity consumed by the lubricators heretofore generally used.

Having thus fully describe-d the construc- `journal-box D and shaft E, when t-he Whole are constructed, arranged, and operated as described, for the purpose set forth.

In testimony whereof l have hereunto sub scribed my name.

AUGUST CONRAD DEWIES.
